Title: A hand tool, such as a garden pruner
Inventor: COOK ANTHONY GEORGE
IPC: B25B7/08
Filed: 1988-12-22
Abstract: The tool has two pivotally interconnected members, each member comprising a blade 13 or 15 or other work-engaging portion and a handle 14 or 16 rigidly secured thereto, and a spring urging the members angularly apart. A catch 30, 31 on handle 16 has an abutment surface 31b for engagement with a surface 13a on the other member e.g. blade 13 to limit opening movement of the members. The surface 31b arcuate eccentrically of the axis of the catch and the surface 13a is generally arcuate about the pivot axis. The catch is rotatable to vary the point in the opening movement of the blades etc at which engagement between surfaces 31b & 13a takes place. The pivot comprises screw-threaded parts 17 (18, Fig 6) and a worm screw (72), the arrangment being such that rotation of the worm screw causes relative rotation of the screw-threaded parts (17, 18) thereby varying the pressure of one member against the other member to take up wear. <IMAGE>

Title: Photographic materials with anti-static coatings
Inventor: CAWSE JOHN LESLIE
IPC: G03C1/89
Filed: 1990-07-31
Abstract: A photographic material comprises at least one silver halide colloid layer and at least one anti-static layer either coated on the silver halide layer or on the side distal to the silver halide layer the said anti-static layer comprising a colloid binder having therein a mixture of a polyoxyalkylene compound and a polymeric salt. The binder is preferably gelatin and the polymeric salt may be the Li, Na, K, ammonium or triethylammonium salt of a polymer containing sulphonic acid units. It is thought that the polyoxyalkylene compound and the polymeric salt form a complex as has been suggested by P V Wright, British Polymer Journal I, 319 (1975). It has been found that this complex produces a much improved anti-static composition over the use of the equivalent amount of the two constituents used separately.

Title: Wood products
Inventor: STICKLAND FREDERICK THOMAS
IPC: B27N3/04
Filed: 1991-05-10
Abstract: A process and apparatus for forming a reconsolidated wood product, and a partially rended natural wood bundle therefor, comprises partially rending natural wood to form a plurality of flexible open lattice work webs each of naturally interconnected wood strands which are generally aligned along a common grain direction with a substantial proportion of the strands in each web being substantially discrete but incompletely separate from each other. Each web is of increased width laterally and correspondingly decreased thickness compared to the natural wood but they may vary in dry wood densities. To avoid this the webs are compacted widthwise to substantially uniform dry wood densities and this may involve weighing the webs and measuring their moisture content. The compacted webs are then abutted width-to-width and partially rended natural wood bundles of preselected widths and dry wood densities are cut from the mat. The bundles may then be at least partly superposed, compressed and bonded together to form the desired product.

Patent GB-2258965-A (GB)
Title: Doppler speed sensor
Inventor: NICHOLLS MALCOLM RICHARD
IPC: G01S13/60
Filed: 1991-08-23
Abstract: A two-beam doppler speed sensor for use on a vehicle uses a single transmitter (11, 12) and receiver (13, 14). Two beams (21, 22) at 90 DEG are generated from a single beam (18) using quasi-optical components (23, 24, 25, 26). The two reflected beams (21', 22') are similarly combined using quasi-optics (29, 30, 31, 35) to give an output (16) from the receiver in which the two doppler frequencies of the beams are averaged spectrally. The beam-splitting components may be dielectric plates (24, 31) or polarisation-sensitive parallel conductor grids. In use, the sensor is aligned so that the two beams make equal angles of incidence (45 DEG ) with the ground, one beam looking forward, the other rearward. When through misalignment the incidence angles are not equal, one beam suffers a high doppler shift and the other beam suffers a low doppler shift, relative to the expected shift. The average peak spectral output from the receiver indicates the true velocity, the high and low doppler shifts effectively cancelling one another. Major advantage is a saving in components over designs which use two transmitters to generate the beams. <IMAGE>
